Population differentiation and speciation in the genus Characidium (Characiformes: Crenuchidae): effects of reproductive and chromosomal barriers
(Wiley-Blackwell, 2014-03-01)
Both time and low gene flow are the key factors by which different biological species arise. The divergence process among lineages and the development of pre- or postzygotic isolation occur when gene flow events are lacking. ...
